WebbPlasmodesmata in plants and gap junctions in animals are functionally similar in that a. each is used to anchor layers of cells. b. they form channels between cells that allow diffusion of small molecules. c. they form tight junctions between cells. d. they are anchored to the extracellular matrix. WebbWhat’s found inside a cell. An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little …
WebbSmall channels that form across the plasma membranes of adjacent animal cells; especially important in intercellular communication; help coordinate activities of … WebbThese junctions allow communication between adjacent cells via the passage of small molecules directly from the cytoplasm of one cell to that of another. Molecules that can pass between cells coupled by gap junctions include inorganic salts, sugars, amino acids, nucleotides, and vitamins but not large molecules such as proteins or nucleic acids. Gap …
